I am hoping someone might be able to make sense of what is going on with my ears or brain, as I can't really pinpoint what the problem is.
Tonight I am completely exhausted, my ears are ringing and I am really tense. My DN has been over with Dsis (we are her support bubble).
When DN and my DC get together, the noise that they make utterly exhausts me. I think I have brought my DC up to be quite quiet and DN is normal child volume. 
The extra noise makes me physically exhausted and unable to function. DS was running around with a noisy toy and eventually DH came downstairs and took it from him, my brain wasn't functioning sufficiently to do that. I also said yes to a big treat that I really wouldn't have done if I had been able to think.
It sounds really petty, but it is actually having a fairly big impact on my life and health. I've never liked a lot of noise and I am sometimes irritated by conversation when eating or in the car.
Both of my parents have some degree of hearing loss, DF has tinnitus and DM has Meniere's Disease. DF is also quite similar in being agitated by the noise of several people together.
I would say though, that my hearing is good, I don't think I have any hearing loss. What is going on?
